title: [Application of air-Q laryngeal airway and gum elastic bougie in a case of anticipated difficult. Mask ventilation and tracheal intubation in a man with morbid obesity].
abstract: A 46-year-old man was diagnosed with descending colon cancer and was planned to undergo left hemicolectomy under general anesthesia. His body mass index was 42.6 and due to his small mouth and jaw, we anticipated difficult mask ventilation and tracheal intubation. To avoid 'can't ventilate, can't intubate', we first inserted a size 3.5 air-Q laryngeal airway under moderate sedation, maintaining spontaneous ventilation. After confirming sufficient assisted ventilation, we used a bronchofiberscope to visualize placement of a gum elastic bougie in the trachea via the air-Q. Then, we replaced the air-Q with an outside diameter 8.5 mm tracheal tube. This case was a successful use of the air-Q under moderate sedation for airway management in the setting of anticipated difficult mask ventilation and tracheal intubation.
